@Joe-von-Habsburg said in Add ready widget into widget: I am leaving an example QtCreator Preferences is your example?! So you want something similar?! You could dig into QtCreator source code and check out how it's done. For this I would use QToolButton to populate the "menu bar" on the left and a QStackedWidget to display the content pages on the right. Actually the QStackedWidget is more like centered, as the whole window you see is divided into two sections (~15% / ~85%) for the menu and the "rest" (the QStackedWidget for the content). Is it Qt designer form class (.cpp && .h && .ui)? The "right side" is the content widget... In case of QtCreator a custom QWidget containing a QTabWidget for the Text Editor settings among many other things. The parent of all this is probably a QStackedWidget as I presumed above. What approach (with or without Designer Form) you pick to implement this has nothing to do with how it works. Both ways are possible.

Hi, Since you mention linking to a library, did you properly export the symbols of that library ?

Hi, From a quick search, there's nothing native for NodeBB but there is a plugin that might help. What do you think @ollipuu ?

@qtmsfp everything setted

Thank you, I hope I'm not overcomplicating this. I just can't seem to see a better solution.

@jeanmilost I can't answer all your questions, as I'm not an expert on Qt's Model/View system, what I do know is, that all models have a QAbstractItemModel as base model and that is also the ABI for all views. For that reason alone, you can assign all models to all views. You will however not get a useful representation of all your data in all views. As I understand it, and anyone fell me to correct me here, the other higher level classes of models are only there to make your life easier, as in you do not have to implement all functions/functionalities of the whole AbstractItemModel class

@jsulm Ok, thanks a lot for the help

@TMJJ001 hi the canvas content is generated programmatically, i'm not sure you can do it in the Designer

Hallo. Wenn Du ausschließlich Qt Widgets benutzen möchtest, so würde ich vorschlagen, dass Du, z.Bsp., Dein Hauptfenster zwei teilst: Das eine Unterfenster soll dann die wechselnden Ansichten zeigen, und das andere Unterfenster enthält dann Dein TreeWidget. Klickt man dann ein Item des TreeWidgets an, wechselt sich die Ansicht im Nebenfenster.

I went with the Binding solution in the end :)

Hi @Larvae, you might get better answers to questions about internal code and design decisions at the Interest mailing list (subscribe first, then post). Qt engineers are active on that list; this forum is mainly used by Qt users who don't necessarily know any internal details.

You have to enable Use QML emulation layer that is built with the selected Qt in the settings, since Qt Creator does ship with Canvas3D. Note that Canvas3D is not officially supported in the designer, though.

Unplugging the tablet does not help. You have to at least temporarily disable the driver. The issue is described in detail here: https://bugreports.qt.io/browse/QTBUG-47548 You can stop the driver like this: net stop WTabletServicePro And restart the driver with this command: net start WTabletServicePro

Hi and welcome to devnet, What kind of transformation do you have ing mind ?
